But to Cowboys defensive coordinator Rob Ryan, it’s a chance to needle his twin brother leading up to their 9/11 showdown at MetLife stadium.

At first, the bearded, long-haired Ryan came to the defense of his brother when asked about the alleged online foot-fetish videos that surfaced last season. You remember, the ones that featured a woman resembling Rex’s wife, Michelle — and a man behind the camera whose voice sounded like the Jets’ boisterous coach.

“Aw hell, who cares?” Rob said on Monday, according to the New York Daily News. “Believe me, everybody has whatever screwed up thing going on. I don’t care. I’m sure you do, and everybody else that points fingers. Who cares? Everybody has a life off the field. Who gives a crap? I’m sure I’m worse than he is. So big deal.”

You can say this about the Ryan brothers: they certainly don’t hold much back.

“I mean hell,” said Rob. “He is a little freaky, I guess.”

“I’ll say this,” Rex said on Monday. “If it’s a personal matter, then you know what my response is going to be: it’s a personal matter. If it was a personal matter then, it will be a personal matter now, tomorrow and years later.”

Rex’s “personal matter” comeback hasn’t changed since the story took on a life of its own last December. Let’s just say Rob was a little more open about his wife’s feet.

“Hell, I don’t know,” said Rob. “I like everything about my wife. She got great feet, too. She got everything nice. What the hell.”

“That’s just the way he is,” said Rob. “This is a big thing for him, a big thing for the Ryans. He’s just about the only guy that’s beaten cancer about every time. He’s been through it about four or five times. I’m sure the prognosis is great for him because he always wins.”

“It’s going to be great having him here,” Rex added from Florham Park, NJ. “I know this is huge for him. He’s looked forward to it for a long time.”
